They can try it forever, but identity politics will never sell comics. That just won't happen. Print comics are not a growth industry. There just aren't that many people will will go to comics shops to buy them.

The idea that you can boost comics sales by casting a Latina and a Muslim as your leads and decreasing the presence of long-established characters is ludicrous. You can pat yourself on the back for being a good person when you do stuff like that, and I'm sure the folks at DC and Marvel do, but you're killing your own business when you diminish the visibility of your stars.

You can be an SJW on your own time. At work you're getting paid to sell comics.
